Resumen
El Accidente cerebrovascular (ACV) corresponde a la segunda causa de muerte en Chile, las estadísticas arrojan que por cada año hay 25.000 personas que lo padecen, ocurriendo la mayoría de los eventos en personas mayores de 65 años. En este estudio determinaremos la variabilidad de los patrones electromiográficos entre las articulaciones de hombro, codo y muñeca del hemicuerpo ipsilateral a la lesión cerebral de usuarios secuelados de ACV pertenecientes al Instituto Luis Krebs ubicado en la ciudad de Viña del Mar, para compararlos con paciente sanos a través de análisis de componentes principales, con esto lograremos establecer cuáles son las reales consecuencias electromiográficas en el hemicuerpo ipsilateral luego de una lesión cerebral. DISEÑO: El diseño de esta investigación se clasifica transversal, no experimental, cuantitativa.
ESCENARIO: La investigación se realizó en la Universidad Andrés Bello sede Viña del mar, ubicada en calle Quillota # 980.
MÉTODOS: 10 sujetos sanos, alumnos de la carrera de Kinesiología de la Universidad Andrés Bello y 4 sujetos secuelados de ACV pertenecientes al Instituto Luis Krebs, que aceptaron de manera voluntaria ser parte de esta investigación.
RESULTADOS: Para los sujetos sanos se logró evidenciar que en el lado dominante con 2 componentes principales se logra el 99% de la variabilidad de la respuesta. Por otra parte, para el lado no dominante se encuentran 3 componentes que logran evidenciar el 100% de la variabilidad de la respuesta. Finalmente en los sujetos secuelados de ACV, con tan sólo 2 componentes principales se logra explicar el 100% de la varianza explicada en el alcance. CONCLUSIONES: El lado indemne (no dominante) de los sujetos secuelados de Accidente cerebrovascular adquiere características similares a las del lado dominante de los sujetos sanos. Por ende, el lado indemne posterior al ACV, se vuelve más especializado, adquiriendo mayor coordinación.
The Stroke is the second cause of death in Chile, statistics show that each year there are 25,000 people with stroke, most of them are happening in people over 65 years old. In this study we will determine the variability of EMG patterns between the joints of shoulder, elbow and wrist of the ipsilesional side of the body of subjects after unilateral stroke from Luis Krebs Institute in Viña Del Mar city, to compare it with healthy subjects through principal component analysis, with this we will establish that the real electromyographic consequences are on the ipsilesional side of the body after a brain injury. DESIGN: The design of this type of research is classified as transversal, no experimental, cuantitative,. INSTEAD OF RESEARCH: The research was conducted in Andres Bello University of Viña del Mar, located in Quillota Street #980. METHODS: 10 healthy subjects, physiotherapy career students of the Andrés Bello University and 4 subjects after unilateral stroke belonging to Luis Krebs Institute, who agreed voluntarily to be part of this investigation. RESULTS: For healthy subjects were able to demonstrate that the dominant side with 2 main components 99% of the variability of the response is achieved. Moreover, for the non-dominant side are three components that make show 100% of the variability of the response. Finally in post stroke subjects with only principal components can explain 100% of the explained variance in scope. CONCLUSIONS: The undamaged side (non dominant) of subjects after unilateral stroke acquires characteristics similar to those of the dominant side of the healthy subjects. Therefore, the healthy side after the stroke, becomes more specialized, gaining coordination.
